and 2 out of 13 tunny were established, the former but a short 

 period of time. 



Nine yellowfin (3 to 6 pounds) died within 1 or 2 days after 

 introduction to the tank, without starting to feed. One, introduced on 

 June 30 (4 pounds), started feeding on July 4 but was caught and 

 stolen by poachers during the same evening. Another, introduced 

 on July 14 (5-1/2 pounds), started feeding on July 22 but stopped on 

 July 26, In obvious difficulty, it was removed from the tank on 

 July 30 and was found to be blind, with bubbles in the eyeballs. 



Eleven tunny {1 to 4 pounds) died within a few days after 

 introduction to the tank. Of these, two started feeding but after 12 

 days becanne blind; one died and the other, in obvious difficulty, was 

 removed from the tajik. Two tunny, introduced respectively on 

 June 16 and August 15, 1952, became established and lived throughout 

 the winter. They were still alive on June 30, 1953. Both weighed 

 about 1 pound when established and grew to about 4 pounds during the 

 year 2/. 



Pond No, 5 



This pond, described in detail by Tester (1952), is about 

 360 feet long and 75 feet wide. The south side is shallow over its 

 eritire length, averaging about 3 feet in depth at high water. The 

 north side includes a deep trough, which averages about 10 feet in 

 depths A slow circulation is effected by tidal action through screened 

 gates at both ends. Both yellowfin and tunny were established in this 

 pond in the sumimer of 1951 but died during the fall, following wet, 

 stormy weather. 



Between July 23 and August 27, 1952, 13 yellowfin (5 to 

 10 pounds) were placed in this pond. Of these, five started feeding 

 and became established. Four of the 5 disappeared from the pond 

 during the first 2 weeks in September--it is suspected that they were 

 caught by poachers, although they may have died "naturally. " In any 



2/ One of these jumped from the tank and died on July 19, 1953. It 

 was partially eaten (by rats or cats?) when discovered, and was 

 not weighed. The other started ramming the walls of the tank 

 and died on July 22, 1953, A film over the eyes indicated partial 

 blindness, which nnay have contributed to its death when alone in 

 the tank. It weighed 3-3/4 pounds at death.
